Ads are automated, no human involved into the actual research of a specific visitor. It's still creepy, but less personal. Some people can accept this line. But I also guess, with AI this line might be moved again.

The deeper reason is probably, machines are following rules, and they do it equally, focus on their specific job, without any hidden agenda. Humans are different, they have personal opinions and their own agenda, they can even be abusive. This is taking control from the people, and many people don't like losing control.
